GAS-MACHINE.

SPECIFICATION forming part of Letters Patent No. 286,865, dated October.16, 1883.` l Application tiled May l1, 1883. (No model.)

chines in which gasoline andother carbonaceous liquids are placed in acarburetor and evaporated by means of compressed air to produceilluminating-gas, and to distribute the same through service pipes toburners in buildings. y

It consists, iirst, in the construction and combination of a series ofoil-reservoirs to produce an independent trap for residuum in eachreservoir, and a continuous and sinuous circumvolving conduit andair-passage, in which sponge is placed to lift and distributethevo1atile hydrocarbon, and thereby facilitate the carbureting process,andto increase the quantity and improve the quality of the gas produced ina given time from a given quantity of oil or gasoline; second, in theconstruction and combination of an air-pump withfthe carburetor in sucha manner as to facilitate adj usting and repairing, to increasethevolume of air and pressure without an increase of power, and also insuch a manner that the pressure in the carburetor, service-pipes, andburners can beeasily regulated,as required,to

` maintain a regular flow of gas and a steady practical use.

light at all times, all as hereinafter fully set forth. I`

Figure 1 of my accompanying drawings is a perspective view, showing thecarburetor and pump mechanism placed inposition relative tokeach otherand a building as required for Fig. 2 is a transverse-sectional view ofthe carburetor. Fig. 3 is a top view of one of my oil-reservoirs, havinga convolute conduit adapted for supporting a perforated sheet-metal orwoven-wire bottom. Fig. 4 is asimilar view, showing a wire bottom in theconduit, as required to support sponge, and to produce a trap forresiduum in the bottom of the conduit and reservoir. Fig. 5 is alongitudinal section of the air-pump and operative mechanism. Fig. 6 isa side view, and Fig. 7 an end view, of the same. Figs. 8 and 9 areenlarged detail views of the pumpbperating 1 mechanism. Jointlyconsidered, these figures clearly illustrate the construction andoperation of my complete invention.

A represents a cylindrical case, preferably made of galvanized iron,within which I form my series of oil-reservoirs andair-conduits.

Nos. 1 2 3 4 are the bottoms of the reservoirs, made of sheet-metalcircular plates, fixed to the inside surface of the case, at properdistances apart, by soldering or in any suitable way to produceair-tight joints. j B represents a continuous strip of sheetmetal plate,bent into convolute form, and fixed at its top edge to the under side ofeach one of the plates 1` 2 3 4 in such a manner as to produce air-tightj oints 5 6 7 represent a series of projections extending in oppositedirections from near the lower edge of each of the reservoir-bottoms.They are formed by simply cutting incisions inward from the lower edge,and then bending the portions between the incisions into right-- angledpositions relative to the plate, so as to extend horizontally for thepurpose of supporting a bottom, C, made of perforated plate onwovenwire. Corresponding projections, 8 9 10, are fixed to the inside of thecase, as clearly shown in Fig. 3. OnV top of these auxiliary bottoms C,I place sponge to fill the convolute conduits in each reservoir. Bybending the sections 6 7 at right angles to the strips B,

openings are produced to connect the space,

and residuum-trap that is produced between the air-tight bottom B andthe perforated b0tV tom C. A

D is an induction-tube, that connects the air-pump with the carburetor,and enters the lower reservoir, No. l, and theoutside of its voluteconduit in such a manner that the air will be forced through theconduit` from the circumference of the carburetor to the chamber D atits center, and from thence to a cor-V responding chamber in No. 2reservoir, through avertical open-ended tube, f, iixed in its bottom;andfrom the center of No. 2reservoir the air will pass through thevolute conduit to the circumference, and from thence up through a tube,f into the No. 3 reservoir. Any number of oil-reservoirs having traps intheir bot- ICO toms may be thus connected, so as to cause air to bepassed through them and into an edu`etion-tube, D2, at the top of thecase A.`

D3 is an induction-tube connected with the tube D2 in sucha manner thatoil can be poured through it into the upper reservoir, and when nearlyfull,it will overflow the tube f and pass down through the tube into thenext reservoir. All the reservoirs can be thus successively filled withoil through the medium of the tubes D2, D, f, and f.

g is a tube connected ywith the top portion of the lower reservoir, andextends to the surface of the ground or cover of the vault within whichthe carburetor is placed, to serve as a vent for the air that will. bedisplaced from the reservoirs by the ingress of the oil.

g are induction-tubes connected with the independent traps in thebottoms of the reservoirs. By attaching a suction-pump to each onesuccessively, all the residuum gathered in the traps can be readilyextracted, and the carburetor-conduits and sponge therein kept clean bymeans ofthe traps.

,. H represents the cylindrical case of my air- ,pump, attached to aframe and the frame fixed to the fioor. It is formed in two fiangedsections, so that the top section can be taken off.

H is a revolving cylinder within the concentric case H. It has a shaft,H2, to which are fixed four spiral flanges, I, to extend along theinside surface of the cylinder from its front end rearward to a pointnear the rear, and' in such amanner as to'produce four open-ended spiralconduits.

H3 is a pivoted bearing fixed to a spring, and connected with the ease Hin such a manner that it will engage a concave in the face of the frontend of the shaft H, to support the revolving shaft, and to press ittoward the opposite end of the case, and a boss or short iianged tube,i, (shown in Fig. 5,) that is bolted against ihe inside and center ofthe end of the case H,-

and a tubular elbow, 7c, having a corresponding annular fiange to engagethe outside of the case. The tube t has an annular shoulder, againstwhich the annular edge of an opening in the center of the end or head ofthe cylinder fits, and against which it is constantly pressed by theforce of the spring connected with the pivoted bearing H3 at theopposite end of the cylindershaft H`Z and case H.

k is a tubular elbow-shaped tube screwed intothe fixed tube i, to extendvertically, and to remain stationary within the vacant rear end of therevolving case H.

Z is a pin fixed to the elbow 7s, to extend into a corresponding boreformed in the end of the shaft H2, to prevent the tube k from droppingwhen it is detached from the boss or tube i.

To detach the tube 7c a screw, 7a, carried in the end of the case H, isforced inward to engage the tube and lock it to the cylinder to berevolved therewith. By combining the screw 7c with the case H, theelbow-shaped tube can be loosened without being touched with the handsand without the use of tools, and the work of separating and repairing amachine greatly facilitated.

m represents a frame fixed to the front end of the case H, to support adrum, mf, that is connected with a suspended weight by means of a rope,as clearly shown in Fig. 1. I

m is a tubular extension on the inner end of the shaft, and m aratchet-wheel on the end of the tubular extension.

mm. is a shaft-bearer fixed within the case H, up on which the tubularextension m ofthe drum-shaft rests and revolves.

'n is a bearer in parallel position with the bearer mm. i

a is a solid shaft, that extends into the tubular end m of thedrum-shaft at one end, and rests on the bearer a at its other end.

a is a hub fixed to the shaft n. This hub has radial arms a, and camsuw( extend laterally from the arms to engage a ratchet-wheel, r, that isplaced loosely upon the shaftoi. Pawls 1,pivoted to theV face of theratchetwheel 1', engage the ratchet-wheel m on the drum-shaft in such amanner that when the drum is revolved the loose ,ratchet-wheel o" willbe revolved therewith, and its arms will engage the cams am on the armsa, that extend from the hub fn, and thereby revolve the hub and solidshaft n', to which the hub is fixed. 1' (shown in Fig. 9) are springsfixed to the loose ratchet-wheel i" and to the arms fri of the hub a insuch a manner that the springs /will in their normal condition hold thecams am on the arms a away from the arms-of' the loose ratchet -wheel insuch a manner that force imparted from the drum shaft will stretch thesprings and store power by so doing before the hub n and shaft a arerevolved. )When the drum m is revolved by means of a crank-handle, r, onits end, as required to elevate the weight and motor power, the forcethus stored by meansof' the springs fr will be exerted to continue themotion of the hub n and shaft n', and the motion and action of thecomplete machine will not be interrupted by the reverse motion of thedrum, and the light will not be extinguished when the weight is down,but only diminished, to thereby give notice that the weight should beelevated again. A pawl, r', (shown in Fig. 9,) prevents any backwardmovement of the loose ratchet-wheel o, to which the springs r areattached and stretched by its forward movement.

s is a chain-wheel fixed to the hub a.

s is a chain-wheel fixed to the shaft H2.

3is an endless chain, that connects the two wheels and. transmits powerfrom the weight and drum to the air-pump as required to rotate thecylinder H. Y

Heretofore coiled springs have been placed upon rotating shafts tocontinue the motion of a revolving cylinder and air-pump while theweight was being elevated; but my manner of combining a series ofsprings with the radial arms and leve-rs of a hub on a shaft is noveland advantageous.

t is a valve-chamber detachably connected with the tubular elbow 7c, atthe rear end of the case H, by means of flanges and bolts. t is acone-shaped valve fitted in the chambert in such a manner that it can beoperated IOO IIO

'pump to the carburetor, but prevent it fro passing backward.

z (shown in Fig. 7) is an opening in the en'd of thetop portion of thecase H, that allows lthe cover or detachable case-section to slip overthe drum-shaft, and also allows air to en- .I ter the case and pump. I5

In the practical operation of my machine the revolving case orpump-cylinder H is half lled with Water, so that the air thatenters theopen ends of the spiral conduits from the outside will be pressedthrough those conduits by the Water which enters as their open ends aresuccessively submerged in the Water, and the air will be discharged intothe rear end of the 'cylinder by the Water, Which performs the functionof a piston, and from thence through the tubes k', 7c, and D into thecarburetor. carburetor Will be lifted by the capillary action of thespongepaeked in the e-onvolute conduits, and thc air forced through willtherefore more readily vaporize the hydrocarbon and increase thequantity of gas and its richness or quality before it passes from thecar` buretor to be distributed through servicepipes to burners.

a' (shown in Fig. 6) represents a stop-cock, for drawing off anycondensedy vapors that may gather in the tube 7c.
